RUDDER MOUNT ING Filed Aug. 15, 1932 lnvenlor j- {id 0 Sula/202 2 I By 2 0g PatentedJuly 4, 1933 PATENT OFFICE OWEN S. LANTZ, OF SOUTH ESSEX, MASSACHUSETTS Iwnnnn MOUNTING Application filed August 15, 1932. Serial No. 628,931.

This invention relates to an assembly of parts which may be broadly referred to as a rudder mounting, and it has more spe- I cific reference to a special type bearing de- '5 signed to effectively accommodate the oscillatory shaft carrying the rudder fin or blade.

The purpose of the invention is to provide a new and improved rudder mounting susceptible of meeting the requirements of a 19 special assemblage of this class, said mounting being desirable in that it is characterized by simplicity, ease and smoothness of operation, dependability and such additional noteworthy features as ruggedness, and durability.

Other features and advantages of the invention will become more readily apparent from the following description and drawing.

In the accompanying drawing wherein like 29 numerals are employed to designate like parts throughout the same:

Figure 1 is a side view, partly in section, showing a structure as developed in accordance with the fundamental ideas and principles of the invention.

Figure 2 is a fragmentary view in section and elevation, on an enlarged scale, showing the essential features.

Figure 3 is a horizontal section on the line 3 8 of Figure 1.

Figure l is a detail elevational view of the clamp equipped sleeve.

Referring now to the illustrated drawing and to Figure 1 it will be observed that the numeral 5 designates the deck of the boat which is formed in its rear end with a vertical bore 6 directly below which is a socketed e tension 7 carried by the rear terminal of the keel 8. The socket in the extension 7 serves to accommodate a trunnion 9 on the lower end of a perpendicular oscillatory shaft 10 which extends upwardly through and beyond the bore 6. On the upper end of the shaft is the usual operating crank 11.

As shown in Figure 2 and in accordance with the principles of this invention a bush ing 12 is fitted into the upper end portion of the bore 6 said bushing being provided at its top with a disk-like attaching flange 13 riveted or otherwise secured to the deck of the boat.

The numeral 14 designates a two-part or split wear sleeve whose upper end portion is enlarged to form aclamping collar 15, said 5 collar being located above the integral inter mediate flange 16. Carried by this collar and located on opposite sides of the slot are complemental flanges 17 to accommodate the clamping and retaining bolts 18. The sleeve 66 14: is dropped down into the bushing and the flange 16 is seated on the plate or disk 13 and the collar 15 is clamped tightly around the upper protruding end portion of the shaft 10. The numeral 19 designates a re 5 tention clip bolted to the plate 13 and having a laterally offset retaining finger 20 which fits over the. flange 16, thereby maintaining the parts in proper relationship and at the same time permitting the requisite oscillatory motion of the shaft and the rudder 21 carried by the lower portion of the shaft as shown in Figure 1.

The essential features of the invention are, first, the bushing 12 fitted in the upper portion of the bore 6 and carrying an attaching plate 13 is a predominating factor. Secondly, the two-part sleeve unit shown in Figure 4 and comprising the sleeve 14, the shouldered clamping collar 15 and the retaining flange 16 is important. This serves as a wear member and the sleeve portion thereof depends into the bushing 12. Then, too, the clip 19 with its laterally offset retaining finger 20 is a distinguishing element. Collectively considered, these parts form a novel and efficient assembly providing an effective bearing and mounting for the oscillatory shaft of the rudder structure. The structure thus constructed is smooth and effective in operation, is susceptible of proper lubrication and maintenance, and otherwise capable of fulfilling the requirements of the invention in gratifying and satisfactory manner.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawing. Therefore,

a more lengthy description is regarded as unnecessary.

Minor changes in shape, size, and rearrangement of details coming within the field of invention claimed may be resorted toin actual practice, if desired.

I claim:

As a new article of manufacture, a rudder mounting comprising a bushing formed with a disk-like attaching plate, a sleeve adapted to fit telescopically in the bushing and designed to surround the rudder shaft,

said sleeve having its upper end longitudiv
